Vanilla JavaScript REST API Front-End GET/POST/CRUD Operations Feasibility

[ARUN R_G_]

Hello all,

Good day

JIRA Software related Cloud or Onsite Custom Front-End Development for Admin and Team Collaboration Inputs.

Problem/Aim: To create a JIRA Front-end with Vanilla JS that can utilize an existing and authorized mechanism of JIRA REST API to query and do REST operations.

I am working on a Proof-of-Concept to develop a Customized Front-End for JIRA Cloud / On-Site JIRA Workspace/Server 

Research done so far:

1. I have went through a set of JIRA community questions from Users and Community Leaders who answered this question - on Vanilla JS when accessed there are CORS Browser policy issue and appropriate backend / proxy to be utilized to overcome the JS-API call instead of browser based call.

2. JIRA Cloud does authenticate the browser to reuse the existing authentication to process the REST API call

Question:

1. Is there a feasibility to utilize Vanilla JavaScript without using any Libraries to make JIRA REST API calls for the Project/Boards etc., with the browser authenticated session (because of the above Research points)

2. Is there anyway JIRA can provide a mechanism to support a custom REST API queries on the browser based JavaScript to build custom applications that are served from an Organization authorized web server and Users already authenticated process.

Thank You so much.

Best Regards,

-Arun
